ok, I've run into a snag..
I know that lots of people have put mech heads on hydro blocks..
but, I have just discovered a major difference between the two, and I need to know what yall are doing about it.
The hydro block/head has two oil ( return?) holes on the front of the engine and the mech one does not..it only has the one in the center..
see the difference in the gaskets:

the block:

and the head I am trying to get on it:

heres how I see it:
the extra hole must be a return hole.. because on the broken hydro head, its just a drain hole.. just like the one in the center but smaller..
so, given that, oil is flowing down... So since the mech head doesn't have the hole, the one in the block will just be blocked and unused.
AM I RIGHT?
with that in mind, I should be able to bolt up the mech head with the mech gasket and be golden.. correct?
but.. I think of another problem: why is the extra hole there on the hydro motor? maybe its because the hydro head is more thirsty for oil, and the block pumps more.. so am I going to be filling the head with oil? and not have adequate draining power? hmmm...
I am really trying to get this sucker running, so, If you have ANY input please post..
THANKS!!!
